I’m using an ender 3 with a 0.4mm nozzle
Looks to me like your temperature is too high and you need to increase your retraction distance.
While turning down temperature might help as it will be less fluid, i tend to think that increasing retraction might give him other problems (unless is settings are really low). On pictures we only see stringing at the top where printing areas are very small which means much more retraction are needed. His issue could be related to maximum retraction count and/or minimum extrusion distance, when those numbers are reached, printer will not retract filament to protect grinding too much filament. Others parameters to look out are retraction speed and prime speed but since OP didn’t share settings, no way to tell what he could try.
To OP, please share your printing settings.
Wet filament can do that. Even new filament can be wet some times, especially with rarer colors that sit around in storage for much longer.
Oh I didn’t even consider this I’ma try this first
This filament has been sitting out for a while so this seems very possible
Well my fdm wont print anything this size so yours is a lot better
make sure everything is as square as you can make it, tension and eccentric wheel not too much or too little, no broken parts, get some filament you dont care about and dry it then go through this:

skip any voron or klipper specific stuff and follow the marlin instructions for each section that has them.
Its a huge pain in the ass to do the whole thing, but you will be able to rule out everything that can be ruled out. Some of the sections are more or less once per printer, some per toolhead change, some are once per filament type, some are per individual roll.
No suggestions. I just wanna know what the answer ends up being that fixes it for you.
